摘要:

我们提出了一种新的图形聚类方法指导下的集群(或社区)的底层结构的额外信息。该问题被公式化为一个图匹配到一个较小的维度的模板,因此匹配$n$顶点的观察图(要聚类)的$k$顶点的模板图,使用其边缘作为支持信息,并放松的正交矩阵的集合,以找到一个$k$维嵌入。与相关的先验知识,编码的集群的密度和它们之间的关系,我们的方法优于经典的方法,特别是对于具有挑战性的情况下。

英文摘要:

We propose a novel graph clustering method guided by additional information on the underlying structure of the clusters (or communities). The problem is formulated as the matching of a graph to a template with smaller dimension, hence matching $n$ vertices of the observed graph (to be clustered) to the $k$ vertices of a template graph, using its edges as support information, and relaxed on the set of orthonormal matrices in order to find a $k$ dimensional embedding. With relevant priors that encode the density of the clusters and their relationships, our method outperforms classical methods, especially for challenging cases.
